1.1 Tilmaamahan waxa uu daboolayaa kuleyliyaha birta ah ee austenitic, kulaylka sareeyo, iyo tuubooyinka kulaylka-bedelka, Fasalada T91, TP304, iwm. Birahaan waxay ku taxan yihiin Shaxda 1 iyo 2.
1.2 Darajooyinka ka kooban xarafka, H, marka loo eego magacyadooda, waxay leeyihiin shuruudo ka duwan kuwa darajooyinka isku midka ah ee aan ku jirin xarafka, H. Shuruudahan kala duwan waxay siinayaan awood sare oo xaraf ah oo ka badan inta caadiga ah ee lagu gaari karo darajooyin isku mid ah iyada oo aan shuruudahan kala duwani ku jirin.
1.3 Cabbirrada tuubooyinka iyo dhumucda sida caadiga ah lagu rakibay qeexitaankan waa 1/8 inji. [3.2 mm] dhexroorka gudaha ilaa 5 inji. dhumucda derbiga ugu yar ama, haddii lagu qeexo siday u kala horreeyaan, celceliska dhumucda derbiga.Tuubooyinka leh dhexroorka kale ayaa la goyn karaa, waase haddii tubooyinkaas ay u hoggaansamaan dhammaan shuruudaha kale ee qeexitaankan.
1.4 Qiimaha lagu sheegay cutubyada SI ama cutubyada inch-pound waa in si gaar ah loogu tixgaliyaa heerka caadiga ah.Qoraalka dhexdiisa, cutubyada SI waxa lagu muujiyay garabyo.Qiimaha lagu sheegay nidaam kastaa waxa laga yaabaa inaanay noqon kuwo u dhigma;sidaas darteed, nidaam kastaa waa in loo adeegsadaa si ka madax bannaan kan kale.Isku darka qiyamka labada nidaam waxa ay keeni kartaa in aan waafaqsanayn heerka.Cutubyada inch-pound waa inay khuseeyaan haddii aan "M" qeexiddan lagu qeexin siday u kala horreeyaan.
SHAXDA 1 Xadka Halabuurka Kiimikada, %A, ee Biraha Alloy hooseeyaA Ugu badnaan, ilaa xadka ama ugu yaraan la tilmaamo.Meesha ellipses (…) ay ka soo muuqdaan shaxdan, ma jiraan wax shuruud ah, falanqaynta curiyahana looma baahna in la go'aamiyo ama la sheego.
